OCT基于MEMS的掃描激光器HSL-40 (1.7μm)

Medical Application High speed scanning laser at 1.7μm can realize deeper penetration into tissue such as arterial wall due to low scatter. It also affords the possibility of Spectroscopic OCT that can further differentiate calcified and lipid rich plaques.

Non-distructive testing Non-destructive testing is one of the key function in product quality control. In-line inspection to detect Void, Crack, Delamination and Defects can be realized by using OCT. HSL-40 delivers fast and accurate measurements with enhanced imaging depth thanks to low scatter at its operating wavelength, 1.7μm.

University of California, Irvine (UCI) has published first paper using our 1.7micron swept source.
Shows promise for cardio-OCT: “significantly improved imaging depth and better identification sensitivity” when compared to 1.3micron imaging.
